Sitting pretty: Heavily pregnant Lara Stone takes the weight off her feet as she relaxes on a bench during a stroll

Her baby is due in May and the strain of pregnancy seems to be finally taking its toll on her.

Dutch model Lara Stone was seen taking the weight off her feet as she had to have a sit down during a leisurely stroll on Tuesday.

The 29-year-old perched on a bench and took in the wonderful views of London from Primrose Hill as she relaxed during her walk.

Lara may be nearly nine months pregnant, but she didn't let her fashion style slip as she dressed all in black for her day out.

The mother-to-be looked cool in her black leggings and matching tight top that showed off her ever growing baby bump.

She added some on trend fashion by wearing a leather biker jacket and a long scarf. With her long blonde hair down over her shoulders and a pair of sunglasses hiding her eyes, the model looked sublime.

Joined by her faithful companion Bert, the twosome headed around enjoying the sunshine and some down time.

Lara opted to choose comfort over style when it came to her footwear as she sported a pair of black trainers, but added an element of chicness with her designer handbag.

While the model kept herself busy on her mobile phone she also tenderly stroked her belly several times.

Lara and husband David Walliams announced the news of their first child last year via his Twitter page.

The Little Britain star said: 'Some
wonderful news. My beautiful wife Lara is pregnant. We are having a
baby! It is due next year and we both couldn't be happier. Dx'

The
pair already have plenty of practice looking after a little one, after
welcoming Border Terrier Bert into their lives last year.

Lara, who dubs herself 'Bert's Mum' on Twitter, has previously joked about the differences in raising a dog and a baby.

She said: 'A baby will probably never be as fun as Bert.'

David and Lara began dating in September 2009 before marrying at London's exclusive Claridge's Hotel in May 2010.
